Workers celebrated last week the completion of the last of the 18 piers, giants of reinforced concrete each rising 40 metres into the air, that will support the new Genoa bridge. PerGenova, the joint-venture between Salini Impregilo and Fincantieri that is building the bridge, reached the milestone in record time, one of several to be met before delivering the project to the city. The first foundation was started on June 24, 2019. In a matter of months, the piles, the foundations and the erection of the piers were then done at an average rate of three per month.

Taking into account their respective lengths both above and below ground, the piers together have a combined height of 1,500 metres, the equivalent of two Burj Khalifa skyscrapers. Above ground, they all measure 9.50 metres by 4.0 metres in order to guarantee a uniform perspective to the structure as well as to quicken the pace of its construction with the use of the same type of external formwork for every pier. The piers are elliptical in shape, allowing the light to slide off the surface and soften the visual impact that the bridge will have in its urban setting. At the moment, 10 of the sections of the deck that will rest on the piers have been installed. Work on this part of the project is relentless. After the setting of the first of three sections measuring 100 metres each, as well as that of a fourth, smaller one on the east side done two days later, the combined parts of the deck that have been raised have reached a total of 550 metres, more than half of its eventual 1,067-metre length.
